Full title and description
Industrial networks - Profiles - Part 2-3: Additional real-time fieldbus profiles based on ISO/IEC/IEEE 8802-3 - CPF 3. This document defines extensions to Communication Profile Family 3 (CPF 3) for Real‑Time Ethernet (RTE), specifying RTE communication profiles and related network components based on the IEC 61158 series (Type 10), ISO/IEC/IEEE 8802-3 and other relevant standards.
Abstract
IEC 61784-2-3:2023 specifies additional real‑time fieldbus profiles (CPF 3) for Real‑Time Ethernet, including the definition of RTE communication profiles, the associated network component requirements, and the RTE performance indicators (for example latency, jitter and dependencies between indicators) needed to characterise and compare implementations. The standard is published in a bilingual English/French edition.

Scope
The standard provides extensions to the CPF 3 family covering Real‑Time Ethernet communication profiles based on ISO/IEC/IEEE 8802-3 and IEC 61158 (Type 10). It defines profile elements, performance indicators, dependencies between indicators, and requirements for network components to achieve the expected real‑time behaviour. The scope includes guidance for configuring and assessing RTE implementations so that suppliers and integrators can ensure interoperability and meet application-level real‑time objectives.
Key topics and requirements
- Definition and extensions of Communication Profile Family 3 (CPF 3) for Real‑Time Ethernet.
- Specification of RTE communication profiles and their required network components.
- RTE performance indicators (latency, jitter, determinism, throughput) and their dependencies.
- Mapping to underlying Ethernet technologies (ISO/IEC/IEEE 8802-3) and IEC 61158 Type 10 semantics.
- Profiles and parameter ranges to support interoperability between vendors.
- Conformance and test considerations to validate performance claims.
- Guidance for system designers on selecting CPF 3 profiles for application requirements.
Typical use and users
Used by industrial automation equipment manufacturers, device and NIC vendors, control-system integrators, test houses, and standards bodies. Typical applications include factory automation, motion control, robotics and other domains requiring deterministic Ethernet behaviour where CPF 3 profiles help ensure interoperable real‑time communications.
